12 players on Sequential Players in Rd. 1 (Same for Min. Moves, but
reverses on even numbered rounds):
1: 1-12 11-2 10-3 9-4 8-5 7-6
Porter is a simple modification to the original Berger tables which started with Player 1 starting with two whites while another player started with two blacks. E.g., with 12 players, 1-6 had white against 12-7 respectively and 7 starts with two blacks. The modification is 1 has white against 12, but 2-6 have black against 11-7. Click here for an example. Crenshaw corrected the same problem, but opponents are in descending order.
In chess, the first opponent has White. For other games or sports this may also indicate color or home/away status, who calls a coin toss, the winner of the coin toss, or ignored. Court Balanced isn't applicable to chess but may be helpful when assigning tennis courts or time slots randomly which may or may not be balanced. It randomly assigns games to columns, but a better resource is here.
